Foundation pit pile casing filling device and construction method

SHEN QINQIN / CHEN LI

The invention discloses a foundation pit pile casing filling device which comprises a vibratory hammer mechanism, a clamping mechanism and a positioning mechanism. The vibratory hammer mechanism comprises a support, the bottom of the support is fixedly connected with a cylinder, the interior of the cylinder is movably connected with a sliding rod, the bottom end of the sliding rod is fixedly connected with a block, the sliding rod is sleeved with a spring, and the two ends of the spring are fixedly connected with the block and the cylinder respectively. The top of the block body is fixedly connected with a baffle through a rod body. According to the foundation pit pile casing filling device, through the arrangement of the vibratory hammer mechanism, the clamping mechanism and the positioning mechanism, after a forward and reverse rotation motor is started, a clamping block can be driven to clamp a pile casing, and after laser emitted by a transverse linear laser and laser emitted by a longitudinal linear laser intersect vertically, the pile casing can conveniently and rapidly find the center point of a foundation pit; through the arrangement, the pile casing filling device is simpler in structure, the production cost is reduced, and positioning of the center point of the foundation pit in the filling process is facilitated.

本发明公开了一种基坑护筒填入装置，包括：振动锤机构、夹持机构和定位机构；所述振动锤机构包括支架，所述支架的底部固定连接有筒体，所述筒体的内部活动连接有滑杆，所述滑杆的底端固定连接有块体，所述滑杆上套装有弹簧，所述弹簧的两端分别与块体和筒体固定连接，所述块体的顶部通过杆体固定连接有挡板；本基坑护筒填入装置通过振动锤机构、夹持机构以及定位机构的设置，使正反转电机启动后能够带动夹块将护筒夹紧，并且横向一字激光器和纵向一字激光器射出的激光垂直交汇后，能够便于护筒快速找到基坑的中心点；通过以上设置，使护筒填入装置的结构更为简单，降低了生产成本，也更加有利于在填入过程中对基坑中心点进行定位。
